Final answer:
Malignant ovarian neoplasms are more likely to torse due to their larger size and irregular surface.
Step-by-step explanation:
The answer to the question is b) Malignant; larger size and irregular surface. Malignant ovarian neoplasms are more likely to torse or twist. This is because they tend to be larger in size and have an irregular surface, which makes them more prone to twisting and cutting off their blood supply. Benign ovarian neoplasms, on the other hand, are usually smaller in size and have a smooth surface, making them less likely to torse.
